I forgot to add that the giant slide releases on the VP9 and P30 series seems like a design flaw. You can pretty much expect auto forwarding with any slightly aggressive reload.
I like to swap them for the shorter version which is available from HK for another $30-50, that helps with thumb interference,
But it still auto forwards.
I love almost everything about HKs in concept, but the Glock/SCD combination is unbeatable for carry IMO. The HKs sit in the safe.
